Off-Road Water Cart Tanks: 22,000L to 34,000L Builds
06 November 2026
Off-road water cart tanks from 22,000 L to 34,000 L for articulated water carts. Ask WET1 about pumps, spray equipment and options for your carrier.
Choosing a tank for an off-road water cart starts with the carrier and the job it has to do. WET1 designs and manufactures off-road water cart tanks for articulated water carts in four capacities, 22,000, 25,000, 30,000 and 34,000 litres, and the equipment fitted can be matched to how the cart will be used on site.
How Do You Choose Between 22,000 and 34,000 Litres?
Capacity affects how often the cart has to refill, how much water it carries and the load on the carrier. A larger tank may mean fewer refill stops, but it is not automatically the right choice. The carrier model, the haul route and the water source all matter, so confirm the carrier’s limits before settling on a size. Have the carrier’s rated payload and your usual haul and refill distances on hand when you get in touch, because they help narrow the choice.
The WET1 range of off-road water cart tanks covers all articulated water cart models, with the four capacities listed on our tanks page.
What Comes With Off-Road Water Cart Tanks from WET1?
The off-road custom-built tank page lists the standard equipment as follows:
- Pipework: All pumping pipework is hot-dip galvanised.
- Filling: A hydrant fill point, an overhead fill funnel and plumbing for suction fill.
- Spray: Three WET1 80A normally closed spray valves, electric-over-air in-cab controls for all sprays and a rear gravity bar.
- Hose reel: A stainless steel hose reel with 20 m of 25 mm hose and a nozzle.
- Lighting: A light bar and bumper with LED lights.
Optional extras listed include a WET1 RM65E water cannon, a front spray kit, a rear pressure bar, side batter sprays, hand rails and ROPS. The final specification depends on the carrier and how the cart will be used, so confirm the inclusions with us before you order.
Which Pump Options Are Available?
The listed pump options are the WET1 1300 and WET1 2000 pumps, driven by Honda, Yanmar, Kubota or Kohler engines depending on the model, plus a WET1 2000 hydraulic drive pump. Not every pump and engine combination is listed for every build, so confirm current options for your carrier before you decide.
Our guide to configuring WET1 systems gives general background on setting up an off-road water cart.
Does a Water Cart Control Dust on Its Own?
A water cart is one part of a site’s dust management, not a guarantee of control or compliance. Safe Work Australia’s Code of Practice on managing risks of respirable crystalline silica in the workplace sets out a hierarchy of controls and lists an effective wet dust suppression method among the control measures. How that applies to your site is a matter for your own risk assessment.
